I want to insert opening balance of Customers,Vendors and Employee when I install compiere for first time. Please tell me, how could I do it ?
Should I Insert the relative balance in "Import JL Journal" or in line tab of "GL Journal" document ?
I assume you have the trial balance right? You got the concept there, use the GL Journal and key in your TB balances. However, if you want to have the details of documents that make up your AR, AP and Inventory, instead of keying the balance as a whole, use a Control Account. You can then change the default account postings accounts for sales, purchases and related inventory accounts. Thereafter, you can key in the details of the AR, AP and Inventory. With the change in the default accounts, the figures should zerorize the control accounts.
